The Lowdown
Alright, folks, Rusty here. Let’s get straight into it. The next 16 days are looking pretty grim for Kennebunk Beach. The truth is we’re staring down a long stretch of nothing but small, weak, and messy conditions. The data shows a score of zero across almost every session, and the combined swell energy is mostly low, with values like 65 (weak) and 44 (weak) – just not enough push to get excited about.
The first decent hint of anything doesn’t pop up until the very end of the run. From Wednesday, August 19th, right through to the end of the month, the swell is tiny – mostly 0.7 ft to 2 ft, with short periods under 8 seconds, and the wind is almost always onshore or cross-onshore, keeping things choppy and blown out. There’s a bit of a clean spell on the morning of Saturday, August 22nd, with some cross-off wind and 2 ft from the ESE, but it’s just too small to bother with. The same goes for the morning of Sunday, August 23rd – a bit more size at 3 ft, but the period is a pathetic 5 seconds, so it’s all chop and no shape.
Then we hit a bit of a weird one. On Thursday afternoon, August 27th, the swell jumps to 7 ft from the ENE, but the period is 6 seconds and the wind is a strong cross-onshore at 16 mph. This is a case of a lot of water moving around but no quality. The combined energy hits 350 (moderate), but the conditions are described as “poor surf conditions” with a score of 0. For a beach break like Kennebunk Beach, this setup looks more interesting for kite surfing than paddle surfing. Too much wind, messy waves.
The next few days settle back down into small, clean but tiny conditions. The morning of Sunday, August 30th, is glassy with 2 ft from the SE, but it’s just a dribble.
The only real standout, and I mean the only one worth mentioning, comes on Wednesday, September 2nd. The morning shows a moderate offshore wind from the NE at 16 mph, with 2 ft swell from the SE and a period of 11 seconds. The combined energy is 149 (moderate), and the comments say “surfable waves but very ordinary conditions.” The afternoon improves a bit with a light cross-off breeze and 3 ft from the SE, period still 11 seconds, and energy at 161 (moderate). This is clean, but the wave size is still small. It’s the best we get, but it’s not a classic. The water temp is about 66°F which is normal for this time of year, nothing unusual.
So, overall, a very quiet run. If you’re desperate, mark that Wednesday, September 2nd, with the offshore wind and clean lines, but don’t expect much. For the rest of the month, the board stays in the car.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
